I've been an avid Harry Potter fanfiction reader since 2008 when my wife got me hooked on them.
Strangely I have never read Harry Potter past the start of book 2 when JKR lost me with the theft of Mr. Weasley's car by Ron & Harry.
I have seen the movies up to Order of the Phoenix but refuse to see movies 6, 7 & 8 after discovering from fanfiction what JKR did with the Harry-Hermione dynamic.
That said I read Harry Potter fanfiction of most types except slash.
My prefered pairings are Harry-Hermione, Harry-Luna and Harry-Hermione-Luna however I enjoy other pairings as well.
I generally avoid Ron-Hermione match ups as this pairing just seems wrong, what does a genius like Hermione see in Ron Weasley. I have however seen this pairing done well on occasion.
I don't write fanfiction, just read it.
